If your PC is very old the most probably, you will not be able to upgrade the graphics.
For example, if your graphics card is most probably affixed on the motherboard using the now defunct AGP (Accelerated Graphics Port). Most newer graphics cards need a PCIe (Peripheral Component Interconnect Express) slot on the motherboard.
In addition, the power supply will not be able to handle the increased power consumption of the card.
So, you will have to upgrade the motherboard, processor, RAM and power supply before you can think of buying a new graphics card.
It doesn't make sense to spend so much on an outdated machine — you might as well buy a completely new PC if you need more performance.
Note that many new motherboards now also come with 1/2GB shared memory graphics on-board , negating the need to buy an additional graphics card.
